2-Ethylpentyl 3-(3,5-ditert-butyl-4-hydroxyphenyl)propanoate

UsesAntioxidant 1135 is a benzenepropanoic acid, 3,5-bis (1,1-dimethyl-ethyl)-4-hydroxy-C7-C9 branched alkyl esters. It is 100% active, hindered phenolic primary antioxidant for processing and long-term thermal stabilization. Antioxidant 1135 prevents the formation of peroxides in the polyol during storage, transport, and further protects against scorching during foaming. Its low volatility and excellent compatibility helps to prevent fogging in automotive applications and to prevent staining of textiles (e.g. furniture, carpeting, head rests etc.). Used for the stabilization of polyurethane flexible slabstock foams. Its typical use levels are between 0.15-0.5%.
